MASSAGE: vrnna'ron.

Application filed September 23, 1925. Serial No. 58,075.

My invention relates to massagev vibrators of the type adapted to becarried on the back of the operators hand and which do not employ aflexible shaft connecting the same with a motor supported by a wheeledpedestal. Y

The objects of my invention are to provide a massage vibrator havingmeans for regulating the degree of vibration, together with a hingedcasing surrounding said means whereby the adjustment of the regulatormay be quickly and conveniently effected; and also to provide avibration regulator which may. be readily removed from the motor sitionto control the degree of vibration. A.

hinged casing surrounds the vibration regulator, and the face thereofpreferably is per- 7 forated so,that when the regulator is replaced by afan to convert the device into a drier, the current of air will passthrough the perforated casing.

One embodiment of my invention is shown in the accompanying drawings, inwhich- Figure 1 is a side elevation of a massage vibrator embodying myinvention;

Fig. 2 is a central longitudinal section, certain parts being shown inelevation;

Fig. 3 is .a front elevation showingthe hinged casing opened;

Fi 4 is a front elevation showing a fan attac ed to the shaft. toconvert the device into a drier.

In the particular drawings. selected for more fully disclosing myinvention, 10 represents a. small electric motor secured to' the baseplate 11 which-has blocks of soft rubber 5 12, 12 arranged on the lowersurface thereof for transmitting the vibration to the hand of F shaftand replaced by a fanfor converting 17 is a slotted arm 18 having theweight 19 arranged in its slot and adapted to be held in adjusted radialposition by means of the a nut 19' to govern thedegree of vibration.

A protective casing 20 encloses the end of the motor shaft and thevibration.regulator,

and in order to provide easy access to the latter, said casing isdivided into two halves connected together by the hinge 21 which isattached to the front end of the motor by the bracket 22. The two halvesof said casing are held in closed position by the pin 23 which passesthrough eyelets 24', 24 in the two halves of the casing and has threadedengagement, as shown at 25, with the front end of the base 11, a knurledhead 26 referably being employed for removing and inserting said pin. .7

It will be noted that my construction en, ables the operator to exposethe vibration regulator conveniently and quickly when it is desired tochange the position of the weight 19. 1

Preferably the front face of the casing is perforated, as indicated at27, so that when a fan such as 28 is substituted for the arm 18 in orderto convert the device into a drier, the currents of air will passthrough said casing.

Having thus described an illustrative em- 'bodiment'of my inventionwithout however limiting the same thereto, what I claim and desire tosecure by LettersPatent is:

i 1. A massa e vibrator comprising in 00111 bin'ation an efectric motor,a rigid shaft for said motor, an arm rigidly attached directly to saidshaft at right angles thereto, a wei ht, means for securing said weightto saif arm in adjusted radial position to re late the degree ofvibration, and means or applying said motor to the back of the operatorshand.

2. A massage vibrator comprising in combinationa'base adapted to besupported on the back of the hand of an operator, an electric motormounted upon the base, a rigid 6 shaft for said motor, a vibrator armsecured to said shaft radially thereof, a weight adjustably secured tothe vibrator arm and means for securing the base and its attached motorto the hand of the operator.

In testimony whereof, I have hereunto 10 subscribed my name this 22ndday of September, 1925.

LOUIS JOSEPH DUPREY.
